Abstract: It is necessary to set up requirement model from multi—angles for describing the essence roundly an d exactly of in· formation system.A modeling method based on the Zachman framework for the requirement engineering of inform ation system is proposed，the mod els for describing requirement from many diferent aspects are constructed，and the modeling fram ework for analyzing the information system requirement is formed.There are four exeellenees of this framework：multi-views，agility in answering changes，being irrelevant to technology ，and eficient integration of the modeling methods in existence.

摘要： 全面而准确地描述信息系统的本质需要从多个角度建立其需求模型.本文提出了一种基于Zaehman框架的信 息系统需求工程建模方法，从多个不同的方面构建了描述需求的模型，形成了分析信息系统需求的建模框架.这种 框架具有多视角、灵活应对变化、与技术无关以及与现有建模方法有效集成4大优点.
